SASH LOCKING AND OPERATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 561,820, dated June 9, 1896.

Application filed January 30, 1896. Serial No. 577,354. (No model.)

To @ZZ wir/0717, it may concern:

Be it known that l, Anneleen L. SCHILLER, of Scranton, in the county of Lackawanna and State of Pennsylvania, have. invented new and useful Improvements in Sash Raising and Locking Devices, of which the follow ing is a full, clear, and exact description.

rihis inven tion relates to devices for raising and locking window-sashes, and is particularly adapted to the single sash generally employed in vehicles-such for instance, as cars-and the object is to provide such a device whereby the sash may be lowered by gravity to an open position and raised to a closing position by the simple arrangement of a drum and flexible connections between the drum and sash, and also wherein the window-sash may be secured at any desired opening.

I will describe a device embodying my invention, and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is an elevation of a window sash and casing having the device embodying my invention embodied therein. Fig. 2 is a vertical section on the line 2 2 of Fig. l.. Fig. 3 is a horizontal section substantially on the line 3 3 of Fig.A 1, and Fig. et is a face view of a clutch-section employed.

Referring to the drawings, A designates a window-sash adapted to slide vertically in a window-casing A', which is open at the bottom, so that the sash may slide downward into the body of the vehicle. The sash slides between the stop-beads c c', and its upper rail is provided `with laterally-extending fingers c2, adapted to engage stop-blocks a3 in the lower part of the casing to prevent the sash from moving entirely ont of the saine.

Secured within a boxing A2 at one side of the window-casing is a frame ci, within which is journ aled a shaft a5. A drum B is mounted on the shaft a5. This drum is designed to be moved longitudinally of the shaft a when it is desired to lower the windowsash, but is adapted to rotate therewith when it is desired to raise the sash. As a means to cause the drum B to rotate with the shaft, I provide a clutch mechanism between the two parts, comprising a pin IJ, extended trans: versely through an opening in the shaft of and adapted to engage in grooves h' in the adjacent end of the drum B. These clutchsections are held in yielding connection by means of a spring B, secured at one end to the frame co4 and having its opposite free end engaged in an annular groove b2, formed in the inner end of the drum B.

A flexible connection B2 extends from the drum B over a pulleyhs, pivoted in the upper portion of the boxing A2, and through an opening in the sash to a connection with the lower end of the side rail of the sash, and a similar connection B3 extends from the drum B over the said pulley b3, thence across the upper end of the sash over a pulley b4, and down the adjacent side rail of the sash to a connection therewith.

A push-pin b5 engages its inner end with the spring B and extends outward through an opening in the front wall of the boxing Ag, or in a plate secured thereto, and by pushing inward on this push-pin the drum B will be moved longitudinally of the shaft o5, releasing the clutch-sections, so that the drum B may freely rotate and allow the window-sash to move downward by gravity. Upon releasing the push-pin the spring will cause the drum B to move to its lookin g position with the shaft c5, so that by rotating the shaft the connections B2 B3 will be wound upon the drum and consequently raise the windowsash.

As a means to rotate the shaft c5 and the drum thereon to raise the sash, I employ a shaft a, having bearings in the frame o4 and one end of which is extended outward and provided with a finger-piece et?. A gear-wheel a8 on the shaft o, meshes with a pinion a9 on the shaft a5, and to prevent a backward Iotation of the shaft a I provide it with a ratchet-wheel aw, which is engaged by a dog ou, pivoted to the frame a4.

It is obvious that thesash may be held at any desired opening upon releasing the pushpin when said desired opening shall have been reached.

Having thus described my invention, l claim as new and desire to secure by Letters Patentl. A sash raising and locking device, coin- IOO prising a rotary shaft, a drum movable longitudinally on said shaft, a clutch mechanismv between the drum and shaft, whereby the said drum and shaft may rotate together, means for moving said clutch-sections into engagement, means for separating the sections, and Iiexible connection between the:

drum and Window-sash,substantially as specified.

2. The combination With a WindoW-casing,v

of a sash movable vertically therein, a rotary shaft arranged at one side of the casing and having a inger-piece extended through the front Wall thereof, a ratchet mechanism to prevent the backward movement of the said
